-# Bessa API Authentication Research
-
-This document describes the authentication flow for the Bessa Web App (`web.bessa.app/knapp-kantine`).
-
-## Overview
-
-The authentication process follows a multi-step flow involving a guest token and user credentials.
-
-### 1. Initial Guest Session
-When the page first loads, it initializes a guest session. This session is associated with a guest token.
-
-*   **Identified Guest Token:** `c3418725e95a9f90e3645cbc846b4d67c7c66131`
-*   **Usage:** Mandatory for the login request itself.
-
-### 2. User Login
-The login request is sent to the `/auth/login/` endpoint.
-
-*   **Endpoint:** `POST https://api.bessa.app/v1/auth/login/`
-*   **Headers:**
-    *   `Authorization`: `Token <Guest_Token>`
-    *   `Content-Type`: `application/json`
-    *   `Accept`: `application/json`
-    *   `X-Client-Version`: `1.7.0_prod/2026-01-26` (Example)
-*   **Request Body:**
-    ```json
-    {
-      "email": "knapp-<EMPLOYEE_NUMBER>@bessa.app",
-      "password": "<PASSWORD>"
-    }
-    ```
-    > [!NOTE]
-    > The employee number entered in the UI is automatically transformed into an email format: `knapp-<number>@bessa.app`.
-
-### 3. Authentication Result
-A successful login returns a session key.
-
-*   **Response (200 OK):**
-    ```json
-    {
-      "key": "dba7d86e83c7f462fd8af96521dea41c4facd8a5"
-    }
-    ```
-*   **Usage:** This `key` MUST be used in the `Authorization` header for all subsequent API requests.
-*   **Header Format:** `Authorization: Token dba7d86e83c7f462fd8af96521dea41c4facd8a5`
-
-### 4. Token Persistence
-*   The token is stored in the browser's `localStorage` under the key `AkitaStores`.
-*   Path: `AkitaStores.auth.token`
-
-## Implementation Considerations
-
-For the wrapper implementation:
-1.  **In-Memory Storage**: The token should be handled purely in-memory (e.g., in the user session) to ensure security and follow privacy guidelines.
-2.  **No Persistence**: Credentials or tokens should never be written to disk in a production environment.
-3.  **Automatic Email Transformation**: The login handler should automatically prepend `knapp-` and append `@bessa.app` to the provided employee number to mimic the official app's behavior.
